Classification of Picard lattices of K3 surfaces

Jussieu, salle 15-25-502

Using my recent results about classification of degenerations of Kählerian K3 surfaces with finite symplectic automorphism groups, we shall consider the problem of classification of Picard lattices of Kählerian K3 surfaces. By classification, we understand their classification depending on possible finite symplectic automorphism groups and non-singular rational curves of K3 if the Picard lattice is negative definite.
